黑莓中的推送消息监听器
我在黑莓中实现了推送通知。它工作正常。但是当我从服务器发送消息时。它显示应用程序是否正在运行，但如果应用程序也未运行，我需要将消息显示为弹出对话框。如何在黑莓中执行此操作。

它包含代码以及关于在后台运行线程进行监听的解释，它显示弹出消息（类似地
尝试推送通知并在通知到达时显示弹出消息），对于推送通知，请使用备用入口点。

it contains code and explaination about runnning the thread in background to listen and it shows pop message (similarly
try for the push notification and to shows pop message when notification arrives) and for push notification use alternate entry point.
